SPECIFICATION forming part of Letters Patent No. 560,369, dated May 19, 1896.

Application led November 5, 1895l Serial No. 568,018. (No model.)

To all whom, it may concern-.-

Be it known that LADOLPH ROTHSCHILD, a citizen of the United States, residing at Paducah, in the county of McCracken and State of Kentucky, have invented anew and useful Automatic Dumping-Car, of which the following is a specification.

The invention relates to improvements in dumpingcars.

The object of the present invention is to improve the construction of dumping-cars, especially those designed for carrying coal and other heavy material, and to provide a simple and inexpensive one which will enable its entire contents to be quickly dumped without necessitating shovelin g at its ends.

Theinvention consists of the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a perspective view of a dumping-car constructed in accordance with this invention, one of the folding end skids being raised and the other being arranged against the adjacent end wall and bottom portion of the car. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is a transverse sectional view. Fig. 4 is a detail sectional view illustrating the manner of mounting the rack-bars and pinions. Fig. 5 is a detail view .of one of the curved shields. Fig. 6 is a detail view of the operating-lever.

Like numerals of reference designate corresponding parts in all the iigures of the drawings.

l designates a dumping-car having its side and end walls arranged vertically and provided at the center of its bottom with a depending hopper 2. The hopper is provided at its bottom with hinged gates or doors 3, which are connected at their free edges by chains 4 with a transverse windlass-shaft 5. The windlass-shaft 5 is provided with a crankhandle, which may be removable or be formed integralV therewith, and the 4shaft is held against retrograde rotation by a pawl and ratchet (i. When it is adapted to dump the car, the pawl is thrown out of engagement with the ratchet and the weight of the material in the hopper will open the gates or doors 3.

1n order to empty the material from the entire car without shoveling and without decreasing the capacity of the car by providing 5 5 permanent inclined end walls forming a continuation of those of the hopper, folding skids 7 are arranged in the car at each end thereof. Each folding skid consists of upper and lower sections 8 and 9, connected at their adjacent 6o edges by a pintle-rod 10, and constructed of any suitable material7 the eyes for the pintle-rod 10 being preferably formed integral with metal strips or bars 11 and 12, arranged at intervals on the upper and lower sections. The upper edge of the upper section is hinged to the top of the car at the adjacent end thereof by an upper transverse pintle-rod 13, and the lower edge 14 of the lower section is beveled and is adapted to slide freely on the 7o bottom of the car when the sections of the skid are raised to an inclined position in alinement with each other to form a continuation of the adjacent inclined wall of the hopper. W'hen the skid is arranged in its folded 75 position, the sections fit squarely against the bottom and end wall of the car and do not decrease the capacity thereof and are not subjected to any strain when not in use. The skid-sections may be constructed either of 8o wood or metal, and when of the former the edge 14 of the lower section is protected by a suitable metal strip, as illustrated in the accompanying drawings.

The skid sections are raised from their 85 folded position at right angles to each other to an inclined position to shoot the material into the hopper by curved rack-bars 15 and short windlass-shafts 16, carrying pinions 17, which mesh with the curved rack-bars. The 9o curved rack-bars are arranged at the inner faces of the sides of the car and are provided at their lower ends with eyes 18, which receive the ends of the pintle -rod 10. The short windlass-shafts are located at each side of the car and pass through the sides, the pinions being arranged on the inner ends of the shafts within suitable keepers 19 and the outer ends of the shafts being adapted to receive an operating lever 2O and carrying Ioo ratchet-wheels 2l, which are engaged by pawls 22, pivotally mounted on the car.

The teeth of the rack-bars are arranged at the upper edges thereof, and the lower edges of the rack-bars are supported within the keepers 19 by antifriction-rollers 23. The keepers 19 are disposed substantially horizontal on the inner faces of the sides of the car, and the outer ends of the short windlassshafts are supported by suitable brackets 24. The operating-lever 2O is provided at one end with an eye to receive the short windlassshaft, and it is secured thereon by a pin 25, and adjacent to the eye the operating-lever is provided with a pivoted dog 2G, adapted to engage the teeth of .the ratchet-wheel 2l to rotate the windlass-shaft l 6,whereby the rackbars are moved upward.

In order to prevent the teeth of the rackbars from becoming filled with coal-dust or other accumulation, the sides of the car have secured to them curved shields 27, substantially triangular in cross-section and presenting inclined faces adapted to shed the coal and dust. The upper section S of each folding skid is provided at its end adjacent to the pintle lO with recesses 28, which receive the curved shields 27, and which causes the skids to clear the saine.

It will be seen that the dumping-car is exceedingly simple and inexpensive in construction, that it is capable of rapidly discharging its entire contents without necessitating shoveling, and that its capacity is not decreased, as it has vertical end walls and horizonal bottom portions. It will also be apparent that the car is not weakened by its dumping at tachnient, and that the folding skids may be readily applied to cars of the ordinary construction without necessitating any alteration thereof. i

Changes in the form, proportion, andminor details of construction may be resorted to without departing from the principle or sacrificing any advantages of the invention.

l. The combination with a car, of a folding' skid composed of two sections hinged together and similarly connected to the top of the car and adapted to fit against the end and bottom thereof when not in use, curved rackbars connected with the skid and located at the sides of the car on the inner faces thereof, gearing arranged to mesh with the rackebars to raise and lower the same, and shields mounted on the car and arranged to exclude dust from the teeth of the rack-bars, substantially as described.

2. The combination with a car, of a folding skid composed of two sections hinged together and similarly connected to the top of the car and adaptedm to iit against the end wall and bottom when not in use, curved rack-bars connected with the sections and arranged on the inner faces of the sides of the car, curved shields mounted on the car and located above the rack-bars and having inclined faces adapted to shed the material to prevent the teeth of the rack-bar from becoming clogged, pinions meshing with the rack-bars, and windlass-shafts connected with the pinions and adapted to raise the rack-bars, substantially as described.

3. The combination with a car, of a folding skid composed of two sections hinged together and similarly connected to the top of the car and adapted to fit against the end and bottom thereof when not in use, curved rackbars connected with the folding skid at the point of hinging, extending upward from the skid and located on the inner faces of the sides of the car, pinions meshing with the rack-bars and mounted on the inner faces of the sides of the car, windlass-shafts connected with the pinions and extending through the sides of the car, and pawl-and-ratchet devices mounted on the outer faces of the sides and connected with the windlasswshafts, sub stantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses. i
